Add/Subtract Dates using the Java Date Translator **Note: This Feature Has Been Deprecated. Please use this link to find alternative features: https://www.mrc-productivity.com/techblog/?p=522     The Java Date Translator is a very powerful tool, commonly used to determine the difference between two dates (Most date conversion can now be accomplished with a UDF). However, there is […]

mrc Date Conversion UDFs (User-Defined Functions)   mrc supplies three date conversion routines specifically for AS/400 databases. These routines are SQL functions located in MRCAPPLLIB, and they are available for use in logical and calculated fields. All three UDFs take a numeric date as an input parameter. Function specifications are described below. UDF Name Description […]

UDF Introduction   All applications created with m-Power employ SQL to access the database. SQL, by itself, is a very powerful language. A database User Defined Function (UDF) allows users to extend the power of SQL. UDF's are a powerful yet simple way to perform routine data transformations, calculations, and complex SQL logic. Database vendors […]
